An example of an amateur radio station,
with four transceivers, amplifiers, and a computer for logging
and for digital modes. On the wall are examples of various
amateur radio awards, certificates, and a reception report card
(QSL card) from a foreign amateur station.
Amateur radio, also known as ham radio, is the use of radio
frequency spectrum for purposes of non-commercial exchange of
messages, wireless experimentation, self-training, private
recreation, radiosport, contesting, and emergency communication.
The term "amateur" is used to specify "a duly authorised person
interested in radioelectric practice with a purely personal aim
and without pecuniary interest;"[1] (either direct monetary or
other similar reward) and to differentiate it from commercial
broadcasting, public safety (such as police and fire), or
professional two-way radio services (such as maritime, aviation,
taxis, etc.).
The amateur radio service (amateur service and amateur-satellite
service) is established by the International Telecommunication
Union (ITU) through the Radio Regulations. National governments
regulate technical and operational characteristics of
transmissions and issue individual stations licenses with a
unique identifying call sign, which must be used in all
transmissions. Amateur operators must hold an amateur radio
license which is obtained by passing a government test
demonstrating adequate technical radio knowledge and legal
knowledge of the host government's radio regulations.
Radio amateurs are limited to the use of small frequency bands,
the amateur radio bands, allocated throughout the radio
spectrum, but within these bands are allowed to transmit on any
frequency using a variety of voice, text, image, and data
communications modes. This enables communication across a city,
region, country, continent, the world, or even into space. In
many countries, amateur radio operators may also send, receive,
or relay radio communications between computers or transceivers
connected to secure virtual private networks on the Internet.
Amateur radio is officially represented and coordinated by the
International Amateur Radio Union (IARU), which is organized in
three regions and has as its members the national amateur radio
societies which exist in most countries. According to an
estimate made in 2011 by the American Radio Relay League, two
million people throughout the world are regularly involved with
amateur radio.[2] About 830,000 amateur radio stations are
located in IARU Region 2 (the Americas) followed by IARU Region
3 (South and East Asia and the Pacific Ocean) with about 750,000
stations. A significantly smaller number, about 400,000, are
located in IARU Region 1 (Europe, Middle East, CIS, Africa).
